The entire algae water separation process can be completed continuously and efficiently on the engineering ship. The engineering ship is mainly composed of an algae receiving cabin (1), a suspension front cabin (2), a suspension rear cabin (7), a concentration cabin (4), an algae collection cabin (3), a floating algae accumulation cabin (6) and a clear water cabin ( 9) composition, is also equipped with filter (8) and centrifuge (5) etc. simultaneously.

Description

A process plan for cleaning floating algae on the water surface and an engineering ship

technical field

The invention relates to the technical field of environment-friendly aquatic algae cleaning and treatment. The characteristic of algae floating on the water surface is utilized to design a new technological process suitable for cleaning the floating algae on the water surface and an engineering ship with a special structure. The absorbed algae water is subjected to a series of treatment such as floating algae collection, concentration, and algae water separation to achieve the purpose of cleaning the floating algae on the water surface.

Background technique

Aquatic algae often spread in lakes and reservoirs, seriously polluting water resources and having a certain impact on people's lives and the natural environment. At present, most of these algae are salvaged manually. Generally, the water surface of lakes and reservoirs is relatively large, and these algae reproduce and grow relatively fast, with small volume and quality. Require. There are also some mechanical salvage methods, but the existing mechanical salvage methods can only partially replace manual salvage, and cannot realize the integration of absorption, concentration, and treatment. Generally, the efficiency is relatively low, and they cannot meet the requirements of timely and efficient cleaning treatment.

Contents of the invention

The invention provides a brand-new technological scheme and an engineering ship for cleaning and treating algae organisms on the water surface quickly and efficiently. The process scheme is realized through the special structure of the engineering ship. The engineering ship is mainly composed of algae water receiving cabin (1), suspension front cabin (2), suspension rear cabin (7), concentration cabin (4), and algae water collection cabin ( 3), the floating algae accumulation cabin (6) and the clean water cabin (9) are formed, and are also equipped with filter (8) and centrifuge (5) simultaneously.

The water surface floating algae cleaning process scheme and the working principle of the engineering ship proposed by this invention are: (as shown in Figure 1 and Figure 2) the mixed algae water drawn from the water surface is first delivered to the algae water receiving cabin (1), and then slowly enters the suspension The front cabin (2) flows into the suspension rear cabin (7) through the front and rear suspension cabin through holes (14), and the algal water passes through the filter (8) and finally the clear water flows into the clean water cabin (9) and is discharged outboard. During the slow flow of algal water in the suspension front cabin (2) and the suspension rear cabin (7), the floating algae floats up, and the floating algae floating on the water surface are sent to the concentration cabin (4), and the floating algae in the concentration cabin (4) also sink in the water. The bottom algae floats up, the water sinking to the bottom flows into the algae water collection chamber (3) through the algae water collection chamber through hole (15), and the algae water in the algae water collection chamber (3) is sent back to the algae water by the water pump. The water receiving cabin (1) realizes the first cycle in the process of algal water treatment, and also realizes the concentrating effect of the floating algae in the concentrating cabin (4). At the end of the suspended rear compartment (7) is a filter (8), which pumps the floating algae suspended and gathered around the filter (8) to the algae receiving compartment (1) to realize the second cycle of algae treatment . Then the floating algae in the concentration cabin (4) is sent to the centrifuge (5), the separated dry algae is sent to the floating algae accumulation cabin (6) for stacking, and the separated algae water is sent back to the algae water receiving cabin (1) , to achieve the third cycle of algae water treatment.

The biggest feature of this invention is that the whole process of algae-water separation is completed on the engineering ship without any chemicals, no secondary pollution, and continuous high-efficiency operation.
